UNITED STATES PATENT OFFICE GEORGE ALBERT HOFFMAN, F MANSFIELD, OHIO, ASSIGNOR roTHE NEW METHOD STOVE COMPANY, or MANsrIELD, OHIO.

GAS-RANGE OVEN.

Application filed April 26, 1926.

The invention relates to an improved gas range oven of the general type disclosed in Patent 849,360, of April 9, 1907, and it is the principal object to provide a construction in which a gas supply manifold for the two burners, may be located in waste space at the rear end of the broiling compartment, permitting the front of the oven and the outer sides thereof to be clear ofv pipes and valves, so that the exterior of the oven may be kept clean with less difiiculty, and the manufacturer is spared the necessity of furnishing a number of nickel-plated pipes, valves or fittings, as the corresponding parts in the improved construction are substantially hidden from view. Moreover, by the improved construction, a better mixture of air and gas is obtained before such mixture reaches the burners of the oven.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Fig. 1 is a top plan view partly broken away and in section, showing a gas range embodying the improved oven construction.

Fig. 2 is a vertical sectional view substantially on the plane of line 2-2 of Fig. 1.

Fig. 3 is a vertical transverse section as indicated by line 3-3 of Fig. 2.

The numeral 5 designates the improved oven as a whole, said oven being divided by a horizontal partition 6 into an upper baking compartment 7 and a lower broiling compartment 8, passages 9 being provided to conductheat from the lower to the upper compartment. This upper compartment is provided with a false back 10 having heat escape openings 11 near its lower end and forming, with the back wall 12 of the even, a heat escape passage 13. This passage communicates with a space 14 above afalse top 15 of the compartment- 7, and this space is provided with the usual vent 16. Air inlet openings 17 are provided in the bottom 18 of the broiling compartment 8. and battle walls 19 rise from said bottom to guide the incoming air upwardly to a pair of parallel burner tubes 20 which extend horizontally from front to rear of the compartment 8, near upper corners of the latter, these burners being disposed beneath flame plates 21.

The general construction so far described Serial No. 104,770.

is disclosed in Patent No. 849,360, above referred to.

In carrying out my improvement, I mount a vertical partition 22 at the rear end of i 8, and in this small compartment, I position a horizontal manifold 28 which extends be- The portions of these plates between the side walls 23 and 24 and has in tegral branches 29 extending forwardly and threaded to receive the rear ends of the burner tubes 20 which ends pass through openings 30in the vertical partition 22. The gas and air inlet end of the manifold 28 is formed, in the present disclosure, by an elbow 31 passing through the inner side wall 23 of the oven and connected by a pipe 32 withthe usual gas manifold 33 for the cooking burners, said pipe 32 having an air mixer 34. I

By housing the manifold 28 in the separate compartment 27, it is shielded to a large extent from the burner heat and it is obscured from view, so that it need not be expensively finished. Moreover, the pipe 32 and elbow 31 are hidden and hence no nickelplating or other similar finishing on these parts is required. In addition to this manufacturing advantage, the air mixer 34 is spaced quite a distance from the burners 20 so that thorough mixture of gas and air must take place before the mixture finally reaches said burners. Moreover, the entire front and outer side of the oven are absolutely clear of pipes, valves, fittings, etc., and hence can be kept clean with greater case.

On account of existing advantages for the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, variations may be made.

I claim 2- I 1. A gas oven horizontally partitioned into an upper baking compartment and a lower broiling compartment, a vertical partition across the rear portion of the broiling compartment providing a small auxiliary compartment, a gas and air manifold -disposed in said auxiliary compartment, bnrners projecting forwardly froinsaid manifold through openings in said vertical partition, and baflies spaced inwardly from said burners for guiding air thereto from air inlets in the bottom of the broiling compartment, the rear ends of said bafiles being secured to said vertical partition.

2. A gas oven horizontally partitioned into'an upper bakingcompartmentand a lower broi'ling compartment, the partitionding means having heat passages adjacent the opposed side walls 0f the even, a false tack for said baking compartinentspace'd for- 'wardly from the oven back wall to provide 20 heat "escape passage, said false back having heat escape openings, a pair of horizontal flame pla tes spaced below the partitioning means and passing'u'nder and in contact with said false back, said flame plates extending from front to back of the broiling compartment and projecting inwardly from'said 0pposed side walls of the oven, a pair "of burners extending from front to rear of the broiling compartment and disposed under said flame plates, a vertical partition forwardly offset from the aforesaid false back, said 'vertioal partition extending vertically from and gas lllttl ll fold disposed horizontally in said auxiliary {compartment and connected with said burners.

In testimony whereof I have h reunto 'affixed my signature.
